摘要

The invention provides for a medical instrument (100, 300, 400, 500) comprising a magnetic resonance imaging system (102). The medical instrument further comprises a subject support (120) with a support surface (121) configured for supporting at least a portion of the subject within an imaging zone (108). The subject support comprises a radar array (125) embedded below the support surface. The medical instrument further comprises a radar system (124) for acquiring a radar signal (144) from the subject. The medical instrument further comprises a motion detection system (122) configured for acquiring a movement signal (146). Execution of machine executable instructions (140) causes a processor (130) to: continuously (200) receive the radar signal; continuously (202) receive the movement signal; continuously (204) calculate a combined motion signal (148) from the radar system and the movement signal; and control (206) the magnetic resonance imaging system with the pulse sequence commands to acquire the magnetic resonance imaging data, wherein the acquisition of the magnetic resonance imaging data is controlled using the combined motion signal.
